Large, contiguous parcels of emergent wetland habitat are rare within the lower Great Lakes landscape. As a result, plant and animal species associated with these ecosystems are steadily declining in most areas of the region. Species such as the marsh wren, American and least bittern, Forster’s tern, common moorhen, black tern, and others are declining. Through careful management and clever stewardship methods, the Detroit River International Wildlife Refuge is able to provide large swaths of cattail habitat intermixed with patches of arrowhead, bulrushes, and pickerel weed – all important plant material used for nest construction on many of the refuge’s units.
